Diving into Mastery Guidance for Educators

Aim

• This week we are really focusing on securing the 7, 11 and 12

multiplication tables. It is really important to be able to recall these facts to help you with mental calculations and to help you with things like long multiplication.

• We would like everyone to practise their TTRockstars each day this

week, but if you have any other ways to help you remember your tables, then please use these methods too.

• If you are already really secure with your 7, 11 and 12 multiplication

facts (you can recall any calculation from 1x7 to 12x7 and 1x12 to 12x12 in about 2 seconds when asked in a random order) then there are a two investigations for you to complete.

• Have fun!

Diving 7 Times Table and Division Facts

Give the missing number in each of these sets of multiplication calculations: 4 x 7 = 28 40 x 7 = 280 400 x 7 = 2800 9 x 7 = 63 90 x 7 = 630 900 x 7 = 6300 Use the answers to the multiplication calculations above to help you answer these division calculations: 28 ÷ 7 = 4 280 ÷ 7 = 40 2800 ÷ 7 = 400 63 ÷ 7 = 9 630 ÷ 7 = 90 6300 ÷ 7 = 900

Jacob is asked to insert =, < or > in each of the boxes in order to make these number statements correct. Answers: 2 × 700 = 70 × 20 12 × 70 < 120 × 70 70 × 70 = 700 × 7 60 × 70 > 70 × 6 Look carefully at each of Jacob’s number statements and explain if they are correct or not. 2 × 700 70 × 20 12 × 70 120 × 70 70 × 70 700 × 7 60 × 70 6 × 70 > < < =

Look carefully at this puzzle and insert the missing numbers that will complete each section of the circle correctly. Clue: How are the numbers in each part of the puzzle related to each other? In each section of the puzzle, the two numbers on the outside edge are multiplied together to make the number closest to the centre of the puzzle. 7 560 7 120 50 70 3500 70 70 840 4900 80

Complete the sentences and calculation to match the picture.

6 lots of 10 beads = 6 lots of 2 beads = 6 lots of 12 beads = 6 × 10 + 6 × 2 = 6 × 12 = 60 12 72 72

Complete the table. Draw It Describe It Calculate It 9 lots of 10 = 9 lots of 1 = 9 lots of 11 =

90 9 99

Possible answers: 9 × 11 = 99 9 × 10 + 9 × 1 = 99

48p ÷ 12 = 4p

Freya bought 12 lollipops that cost 48p altogether. How much did one lollipop cost?

11 and 12 Times Table Deeper

Solve the calculations. Which is the odd one out and why?

1 × 11 = 88 ÷ 8 = 132 ÷ 12 = 12 ÷ 1 =

11 11 11 12

12 × 1 = 12 is the odd one

• ut because it is the only

calculation with the answer 12. The answer to the other calculations is 11.

11 and 12 Times Table Deeper

All multiples in the 12 times table are even. Read the statement below. Is it always, sometimes or never true? Explain your reasoning. This is always true. The multiples for the 12 times table are always even because 12 is an even number. It doesn’t matter how many twelves there are - the total will always be even.

11 and 12 Times Table Deepest

The sweet shop sells gummy bears and chocolates. There are 11 gummy bears in each bag and 12 chocolates in each box. Claire buys 47 sweets

• altogether. How many bags of gummy bears and how many boxes of

chocolates did she buy? 1 bag of lollies = 1 × 11 = 11 lollies 3 bags of chocolates = 3 × 12 = 36 chocolates 36 + 11 = 47
